雨水调蓄池容积的简易计算方法探讨

Discussion on Simple Calculation Method of Rainwater Regulating Storage Tank Volune

真如城市副中心因地区功能定位的提高,局部区域的暴雨重现期由P=1 a提高到P=3 a,导致已建排水系统中部分排水设施无法满足设计标准,雨水管道须翻排,雨水泵站须扩容。设置雨水调蓄池可在减少已建排水设施改建工程量的基础上,提高已建排水系统的设计标准。该文以真如城市副中心增设雨水调蓄池方案为例,使用目前几种较为常用的调蓄池容积简易计算方法确定调蓄池的容积,分析影响雨水调蓄池容积的因素,为类似工程的计算提供参考。

In the urban sub-centre of Zhenru because of areal function enhancement,the recurrent period of rainstorm in the partial area is enhanced from P=1 year to P=3 years,which results in the partial drainage facilities in the built drainage system are hard to satisfy the design standard.The rainwater pipelines have to relay and the rainwater pumping stations have to be extended.The setup of rainwater regulating storage tank can enhance the design standard of built drainage system on the basis to decrease the reconstruction engineering quantity of the built drainage facilities.Taking the scheme to add the rainwater regulating storage tanks in the urban sub-center of Zhenru as an example,the article uses the several more common simple calculation methods of regulating storage tank volume to determine the volume of regulating storage tank,and analyzes the factors to affect the volume of regulating storage tank able to be referred for the similar projects.
